COMBINED RADIATOR AND UMIDIFIER.

Application filed December 10, 1923. Serial No. 679,648.

To 1U ywhom t may concern.:

Be it known that LSAMUEL C. XVILSON, a citizen of the United States, .and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Combined Radiator and Humidifier; and I yhereby declare that the following is a full,

` der to humidity the atmosphere of the room in which they are placed. These trays, however, have to be frequently `replenished with water as the latter evaporates and further thelamount of water vapor so supplied is relatively small as the tray and water therein do not receive any heat directly from the s-team in the radiator.

One of the objects of the present invention is to provide a humidifier which is fed with water or water vapor from the heating system.

Another object of the invention is to pro? vide a humidifier which is fed with con-A de1ised \vater from the steam introduced into the radiator with which it is connected.

Other and further important objects of this invention will be apparent from' the disclosures in the specification and accompanying drawings.

This invention (in a preferredv form) is illustrated in the drawings and' hereinafter more fully described.

On the drawings: v

Figure l is a side elevation of a radiator fitted with a humidifier constructed in accordance with the present invention.

Figure 2 is a section on theliue 2-2 of Figure 1.

Figure 3 is a sectionl on the line S-Zfof` Figure 2.

Figure 4 is a section on the line 4-4 of Figure 3. y

Figure 5 is a section on the line 5-5 of Figure.

The invention is shown as applied to a steam radiator of usual construction composed of a series of units or coils 10 bolted together. Between two of these units is arranged a double unit 11 with a rectangular frame 12 formed integrally therewith vand extending laterally therefrom. Fitting in a recess in the outer portionof this frame is la plate 13 of porous material arranged between a pair of grids 14 and 15. Gaskets 16 of rubber'or other suitable material provide a watertight connection and at the same time allow for differential expansion of the plate 13 and the adjacent parts ofv the radiator.

The plate 13 may be made of a wide variety of porous materials such as wood, unglazed earthenware, felt or the like. The plate 13 and the frame 12 enclose a chamber 17 wholly separated from the interior 18 of the steam coils formed integrally therewith except for `conduits 19 and 20 leading to the bottom and top of the cham-j ber respectively.

Passage of fluid throughl conduit 19 is lcontrolled by means of a valve 21 "on the lower end of a spindle 22 passing through and in threaded engagement with a gland 23in the upper part of the frame 12. In a similar manner passage of fluid through theV conduit 20 is controlled by a valve 24 on a spindle 25 passingV through and in threaded engagement with a gland 26. Hand wheels 27 and 28 are provided for turning the spindles 22 and 25.

In operation the chamber 17 is preferably kept filled with water so that 'the latter is in contact with the porous plate 13 and can passtherethrough by capillary 'action and evaporate on the surface exposed to the atmosphere. For this purpose in operation the valve 21 is closed and the valve 24 opened so that steam can enter the chamber 17 and by condensation gradually lill the same up to the level of the conduit 20. The chamber may be drained at any time by opening the valve 21.

I am aware that many changes may be made. and numerous details of construction may be varied through awide range without departing from the principles ofgthis invention, and I therefore do not purpose limiting theA patent ranted hereon, otherwise'than necessitated by the prior art.

I claim as my invention:

1. A humidifying device comprising steam coils, a chamber formed integrally with said steam coils and having fluid connection with the interior of said coils and a porous medium forming a part of one wall of said cha-mber exposed to the atmosphere on one side and to'- uids within Said chamber on the other side.

2. A humidifying device comprising steam coils having a recess in one Wall thereof and a porous medium covering said recess to' 'form an enclosed chamber, said `chamber v v having fluid co-nnectlon with the interior of said coils. v

3. A humidifying device comprising steam coils having a vertically arranged recess 1n one Wall thereof,` a porous medium coverlng sald -recess to form an enclosed chamber, and valve controlled connections `bc-vl SAMUEL C. WILSON.
